mineralise

Catalogue: GRDC Media
Understand the factors that affect mineralisation.. The rate of mineralisation varies with soil temperature, water content and, depending on the soil type, it can vary with the amount of organic matter and residues, and pH - mineralisation is slower in acidic soils... During the growing season, the amount of mineralisation is reasonably predictable and models are available that will estimate mineralisation over time periods ranging from days to years...

Nitrogen is vital to crop growth but it is mostly present in soil in an organic form that plants cannot take up... Organic nitrogen typically accounts for more than 90 per cent of all nitrogen in soil but usually is not directly available to plants... The ratio of carbon to nitrogen in residues is a deciding factor whether nitrogen is removed or released in the soil...

Not only do summer weeds rob growers of valuable soil moisture and nitrogen, recent research suggests it is also robbing growers of substantial profits through large yield losses... New South Wales Department of Primary Industries research and development agronomist Colin McMaster has led much of the research into the effects of summer weeds on plant available water and nitrogen in following crops and the yield benefit from controlling summer weeds... Temperature, moisture and organic carbon percentage are key drivers for nitrogen mineralisation a great opportunity for growers to build free nitrogen during the summer months when seasonal conditions allow...
